it :lrnOWn that we Russian. T. MURRAY and JOHN lVrLnY Tnsnnn, citizens of the United States, residing at Laporte and hilichigan City respectively in the county of Laporte and State of Indiana, have invented certain new and useful improvements in Fluting Machines; and we do declare the followingtobe a full, clear, andv exact description of the invention, suclras Wlll enable others skilled in the art to which it appertains to make and use the same. r Our invention relates to improvements in devices for tinting numerous kinds of ma- 5 terial. the present invention being so designed that it operates to great advantage for fiuting the starched material used externsively in the manufacture of religious bonnets andthe like, although it is to be understood that the invention is in no sense restricted to this use. 7

I One object of our invention is to provide afluting niaohinehaving a plurality of nor mal'ly retracted fiuting irons which may be projected for use as required, novel provision being mate for heating said irons while they are retracted and for again retracting said irons after they have accomplished their functions.

()ther objects are to provide a novel arrangement of tinting irons; to make unique provision forguiding and operating said irons; to provide a novel dog and actuating mechanism therefor, for the purpose of projecting the fluting irons successively; to provide for returning this dog-to starting position after the last iron has been projected; to provide a plurality of key-controlled latches for holding the fiuting irons in projecting positions; to provide novel means for retracting the fluting irons when the latches are released; to devise a unique mechanism for adjusting the heater toward and from the 'iiuting irons as required; and to 5 make novel provision for permitting some heat to escape from the heating casing whenever the temperature rises above a predetermined degree.

With the foregoing and minor objects in view, the invention resides in the novel construction, combination and arrangement of parts hereinafter described and claimed, thedcscriptive matter being supplemented by the accompanying drawings.

In the drawings above briefly described, we have shown a preferred form of construction and in the following, such con struction is described in detail. It is to be understood however that the present disclosure is for illustrative purposes only and that the details set forth need not necessarily be followed, should other equivalent arrangements be found more desirable.

The numeral 1 designates a rectangular casing supported by legs 2 from a suitable table or the like 3, the top 4 of said casing being provided with a hot-air outlet 5 controlled by a damper 6 on a counter-balanced arm 7 controlled by a thermostat 8 through the medium of any suitable operating connections. Arm 7 is preferably fixed on a rock shaft 9 carried by the casing and this rock shaft is provided with a depending crank arm 10 which is operated from the thermostat 8 through the medium of an appropriate crank shaft or the like 11. An electric or other heater 12 is located in the the casing 1 and the thermostatic damper .6 either permits or prevents the escape of heat from said casing, according to the temperature in the latter.

As shown most clearly in Figs. 3 and 4, the

heater 12 is horizontally elongated and is positioned between the upper and lower reaches 13 and 14 respectively of a plurality of U-shaped tubes 15, the upper reaches of said tubes extending entirely across the casing while the lower reaches 14 are shown extending only about half way across said casing, with their inner ends secured in spaced relation by a transverse bar 16. The tubes 15 carry, in their upper reaches 13, a plurality of rod-like fiuting irons 17 and said reaches are so related that these irons are disposed. in two vertically spaced rows, the irons of the upper row being disposed in staggered relation with respect to those of the other row as shown clearly in Figs. 2 4- and 11. The lower reaches 14 are re lated in the same staggered manner as the upper reaches, and said lower reaches carry horizontal operating rods 18 for the fluting irons 17, said rods and irons being connected by means of wires 19 located in the tubes 15 clearly shown in Fig. 3. It thus follows that when the rods 18 are projected from the casing 1, the fluting irons 17 are retracted, whereas forcing said rods into the casing projects the irons for use. For moving the rods 18 in a manner to retract the irons 17, we employ a plurality of coil springs 20 secured at one end to the casing while their other ends are connected with lugs 21 on the rods 18, said lugs extending outwardly through slots 22 in the reaches 14.

For holding the rods in iron-projecting position against the tension of the springs 20, an arrangement of latches is provided, said latches being preferably mounted on and positioned under an apron 23 which extends forwardly from the casing 1 under the fluting irons 17 The details of the latches are shown most clearly in Figs. 3, 8, 9 and 10. A plurality of main latch levers 24 are fulcrumed on a horizontal. rod 25 and disposed in parallel relation with each other, the inner ends of said levers being turned downwardly to provide noses 26. Supplemental latches 27 are pivoted at 28 on opposite sides of the levers 24 and have their inner ends turned downwardly to form other .noses 26 disposed on opposite sides of and spaced from the noses 26. The several noses 26 and 26 are adapted to seat in notches 29 in the rods 18 as shown clearly in Fig. 3, springs 30 being employed for moving the levers 24 to active position, while other springs 31 are used to move the latches 27 into engagement with their respective notches 29, independently of, any movement on the part of the levers 24. The latches 27 and levers 24 however are con-. nected with each other by means of a suitable pin'and slot connection 32 so that when ever lever 24 is operated to release its respective nose 26 from one of the rods 18, the two adjacent latches 27 will be simultaneously moved to retract their noses 26 and release the two rods which they have" previously been holding. Thus, although each lever 24 and the latches 27 carried thereby are independently movable to operative position so as to hold the fiuting irons 17 when they are projected one at a time, these three latch members are simultaneously releasable so that the springs 20 may act to simultaneously return three of the fluti-ng irons to their retracted positions within the casing 1. This is of advantage for several reasons, the most important of which is that it simplifies the operation of the machine and reduces the number of keys or finger-pieces which are used for releasing the latches, such keys or finger-pieces being located on the outer ends of the latch levers 24, as indicated by the reference numeral 32. i

The mechanism for-shifting the rods 18 inwardly and thereby projecting the fluting irons 17 for use, includes a horizontal carriage bar 33 which extends across the casing 1 below said rods, being suitably guided by passage through openings 34 in the casing wall. The front end ofthe bar 33 carries a dog 35 for successively engaging the rods 18 when the latter are projected to the position shown in dotted lines by Fig. 3 and shifting said rods inwardly to the full line position of this figure, so as to project the flirting irons 17. For moving the rod 33 forwardly and rearwardly to operate the dog 35 in the manner set forth, any preferred means may of course be employed, but we prefer touse a foot lever 36 for forcing said bar rearwardly and a coil spring 37 for pulling said lever in such a manner as to move the bar 33 forwardly. Thus, every time the foot lever 36 is operated, bar 33 is shifted rearwardly and dog 35 forces one .go'fethe reds 1 8 into the casing :1, thereby si- .44 laterally to the limit iallowed.

:mult-aneously projecting 'the tinting iron 17 which is connected with said rod. When the foot lever 36 is released, the spring 37 returns the .bar 33 .to its forward position and the dog then engages the outer end of the :neXt-rod 18, in readiness for shifting said rod to project the next flutingiron at at-he Jrequired wmoment.

Although numerous arrangements might beemployed for inountins the dog the .(construction shown is preferable, this construction being illustrated .most clearly by Figs. "5, 6, 7 and 14: to. 17. The :front end of bar is :provided with a Tehead 38 having a longitudinal slot 39 or other guidexwayifor a dog carrier 10 which is brefe ably of the channeled form shown, the bottom ot said -.carrier being provided with a rib l-i received in theslot 3.9 to prevent rotation of said -ca:rrier about a stud 42 which deip'BIldS therefrom through the slot. this stud being slida-bly received in a slot as in a dog shifting armed which is pivoted at 4.5 to bar A spring 426 acts on the arm 44 to constantly exert a tendency :to move said arm *trom the position shown in Fig. 1 to that disclosed in Fig. 6. It thus follows that after the dog 35 has shifted one red 1-8 into ithe casing :and :relases said rod. the arm 44: arnoves said dog and its carrier inwardly so that the dogslides back along; the next :adjacent rod 18 when the spring 37 returns the :bar 33, ltl'llS operation being. indicated in diagram in Fig. 12. Furthermore, when the *dog 35 has reached the limit 01. its return movement, the spring-moved. arm 44 acts to further shift said \dog laterally so that its rod-engaging notch 47 will be properly engaged With the :next rod to be shitted as shown in Fig. 13.

Affter the last rod 18' has beenniovcd in -wardlysinto the casing. and the bar-38 starts to return toward the front 0f{tl1Q mLCl1lI16, thedog disengages the rod last shifted iaznd permits the spring 46 :to throw the arm This SGIVQS 'to seat a ;pin :or other projection 57 lcarnied by the arm 44:, in the forked end 58 105 a pivoted resetting arm 59. Previous to this, :the arm :59 has been held in the posi- --tion shown All] :5, by means of a coil spring .60 andstop screw 61 and said arm -is-umnolested until the arm 44 hasymo'ved ifiromztheposition shown in 5 :to -that;de-

.picted in 6. As above stated however, nahen ithis relation of parts is reached. the

' epin 57 and fork 58 are interengage'd as clearly shownin Fig. i6,:the result being that ias ha-r533 a-nc'lassociated .parts comnlete their :movement toward :the front of the mach: e, ithe arm 59 swings to the position shown in Fig.7 :therebyzreturning the arm 44: and the dog carrier-40 130 starting position. In the am ea ntirne, is :nurnber ot the first irons 17 which were projected, have been returned into the casing l and the rods 29 correspondingly projected and in order that the dog may pass under N projected rods. we pivotal'ly mount said dog i'ior downward swinging as indicated in Fig. 14-. a suitable spring 62 being; employed however for righting;- said dog and holding in upright position after it has passed the rods. The is pivotally mounted in the channel of the carrier 4:0 and the spring 62 is socured in said channel as shown.

Preferably used in conjunction with the features above described. is a incooanisrn for adjusting the heater 1?? toward and from plished by orovioing the heater with several depending; projections 63 (Figs. 3 and 4) which are slidahly received in horizontal partition with which the casing 1 is provided, one of said projections having a cam surface'65 on its lower end go-operable with the tapered end 66 of set-screw 67 so that by adjusting said screw, the heater 12 may be raised or lowered as required.

in operation, all of the iiuting irons 17 are retranad into t e casin 1 so as to be heated by the electric or other heater l2. J fhen the proper temperature has been at- .d. the first iron 17 is oroiected by pushing upon the foot lever 36. The strip S Oi starched or other mater al to be fluted is looped .nd is iron. the next iron is then iro ectechthe strip is looped around the 5'" 1e. and so on until the required length of f'illtlng is irodiiced as will be clear by .ierence to 11. Before the entire {flu operat'on is completed, the irons were first rojccted. have entirely strip 5% and if left longer in contact .nerewith, would scorch the sanie. Therefore, these irons are returned into the simply by pressin the keys and releasing: the rods 18 so that the springs 20 may act. the stri s of tintingv are completed, they may well laid n carried by the top of the ca:

the t :11? y porspecific des it may be well to forth that the moment ("1 released. the se etu the bi -tron.) the pc on shown in. Fig. 3 to its oremcst posyion. which ime. the snring the arm 54; so t 36 acts upon the do s shifted late-rally into engagement age next rod it as shown in diagram in Fig. 13. ll hen the oot lever is a op erased, the last named is forced into the casing: and is held by one oi..-the latches 2%27, the result being that the iron 17 foot .lerer is with 1 connected with the rod is projected for use and held n this projected position. During each return movement, the -:log 335 slides along one of the rods 15 as depicted in 12. but as soon as it reaches the outer end of this rod, it engages the same as shown in Fig. 13 so that it is .in readiness to inwardly shift the red when required. in order to retract any of the irons 1?, it is merely .ne essary to operate the keys 32 thereof, whereupon thev springs 20 immediately come into play.

When the last rod i8 has been inwardly shifted and the bar 33 and associated Pfli'iTS return toward the front of the machine, the

pin 57 and fork 58 interengage as shown in Fig. 6 and the resetting 59 swings from the position disclosed in this figni e to that illustrated in Fig. 7, thereby forcing the arm 4A laterally against the tension of its operating spring i6, positioning the dog at the starting point. lVhen this dog encounters any of the rods 18 which have been returned to their projected positions, it merely yields downwardly as disclosed in Fig. 14: and passes under said rods. being eventually returned to upright position by the spring 62.

Since excellent results may be obtained from. the several features of construction shown and described, such features may be followed if desired, but as above suggested,

it is possible, within the scope of the invention as claimed, to make numerous changes.
